I have a question that has got me real confused. I searched the forums and could not find the exact answer that i am looking for. the question is long winded so I think if i bullet the issues that would be easier, so here I go: 1. I use multiple programs and websites to download hotfixes for xp(windows update downloader, Ryan VM, Offline Update, Microsofts website). which inherently creates many duplicates but also from my research fills holes. 2. I want to use Nlite to integrate all of the above Hotfixes/Ryan VM Pack's. But I am unsure if Nlite can differentiate and know what to overwrite between KB Hotfixes and the Ryan VM Packs. I am sorting by build date just to let you know. If there is a need to do something different to make sure that nlite overwrites and integrates the most up to date files, let me know 3. I have done some initial testing and it doesnt seem like I am getting a very good result. For example I slipstreamed SP3 and then chose all critcal post sp2 KB fixes & Ryan VM Pack and then started nlite. I never got prompted if i want to replace/overwrite older/newer files(like I have been prompted in the past). Wouldnt the above example prompt many overwrites as sp3 should have all these fixes integrated. In Closing. All i am trying to do is make sure that I have a full and completely update version of windows XP . So someone please help, i have been doing so much research on the sp3 release, and the additional hotfixes i need to add(dx, media player, .net, etc) and i keep getting conflicting opinions. so I decided that i should go straight to the source to get the answers i need. I know this was long winded so if any clarification is needed please let me know. Thanks, Thanks, thanks a lot for the help.
